This question related to engine with carburator.
I would like to understand why the engine run evenly and smooth when the air/fuel mixture is lean?
I understand why the engine run evenly and smooth while the mixture is rich and why the engine run rough with too rich mixture, but I don't understand why when go from rich mixture(while the engine run evenly)to the 1:14.7 fuel/air ratio, the engine start to run rough(~ 1 lambda), but if we pass the 1:14.7 ratio into the beginning of the lean mixture area, the engine start to run evenly and smooth again?
What is happening?
Thanks in advance.
have the same problem?
